narrative: |
  turso.tech is built on a near-black canvas (rgb(13, 19, 24)).
  The system uses rgb(79, 247, 209) as the high-saturation accent for primary actions.
  Fully-rounded CTAs (9999px) signal a friendly, tactile interaction model alongside __Inter_f367f3 as the primary typeface.
  __Inter_f367f3 is paired with __Inter_Fallback_f367f3 for secondary roles.
  Depth comes from borders and surface contrast rather than shadows — a flat, structural elevation model.
  Motion is a first-class concern — 11 keyframe animations plus transition-driven interactions.

# Design System — turso.tech
> Extracted automatically by Prism from https://turso.tech
> Date: 2026-06-11
> Viewport: Desktop 1440x900 + Mobile 390x844
> Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted).

> ⚠️ **LOW-CONFIDENCE CAPTURE** — this extraction likely sampled an app shell / interactive demo, **not** the marketing page. Signals: button labels look like filenames (COMPAT.md); only 0 card component detected. Treat the component, color and copy values below with caution, and re-extract the canonical marketing URL if fidelity matters.


## 0. Design DNA

**Density**: sparse  |  **Motion**: expressive  |  **Weight**: heavy  |  **Aesthetic**: dark-premium

| Dimension | Value | Signal |
|---|---|---|
| Canvas | dark | `#0d1318` |
| Type posture | sans-led (__Inter_f367f3) | "Millions of Databases.One Arch" |
| Color assertion | dual-accent | #4ff7d1 |
| Whitespace | sparse | section rhythm 104px |
| Interaction | expressive | 11 keyframes, 5 transitions |
| Radius language | soft-pill | from token scale |

**Prism fingerprint**: `dark-canvas · sans-display · dual-accent · soft-pill · expressive-motion`

> **🤖 TL;DR for AI agents** (read this first — saves you scanning the full doc):
>
> - **Canvas**: `rgb(13, 19, 24)` is the page background. Every component composits against this.
> - **Accent**: `rgb(79, 247, 209)` for primary CTAs ONLY. Never decorative.
> - **Body type**: 16px (token: `typography.body`). Default for ALL text not in a heading role.
> - **Section rhythm**: 104px between major bands. Card padding: 88px.
> - **Default radius**: 12px on buttons/inputs. Pills (`9999px`) only for icon-buttons or status chips.
> - **Forbidden**: Do NOT introduce heavy box-shadows — this system relies on borders for separation
>
> **Before generating UI**: import this DESIGN.md, scan §2 (Color Palette) + §4 (Components) + §10 (Agent Guide). Skip §11–12 unless extending.

## 1. Visual Theme & Atmosphere

turso.tech commits fully to dark-mode as the native medium, not as a toggled alternative. The canvas is a dark surface (`#0d1318`) where elevation is communicated through subtle white-opacity gradations rather than traditional shadows — semi-transparent white borders act as the primary depth indicator, like wireframes etched in moonlight. 

Typography is anchored in **__Inter_f367f3**. 

Body text reads in Pure White (`#ffffff`). **#4ff7d1** (`#4ff7d1`) is the single high-saturation color in the system — it earns its presence only on interactive elements, making CTAs and links the unmistakable focal points against the otherwise neutral palette. Shadow is absent by design — depth is conveyed through translucent borders and luminance steps rather than light simulation. 
Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. Motion design uses smooth easing curves for polished state transitions. 

**Key Characteristics:**
- Background: Jet Black (`#0d1318`)
- Primary typeface: __Inter_f367f3
- Primary text: Pure White (`#ffffff`)
- Accent: #4ff7d1 (`#4ff7d1`)

## 4b. Component Behaviors (State Matrix)

### Interaction State Narrative

- **FooterLink**:
  - **hover:** text #c5cace → #c7ccd0, border changes

*State transitions extracted via Playwright simulation — exact values in the YAML matrix below.*

```yaml
component-behaviors:
  button:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(156, 163, 175)"
  link:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(13, 19, 24)"
    hover:
      bg: "transparent"
      fg: "inherit"
  navLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(255, 255, 255)"
  footerLink:
    default:
      bg: "rgba(0, 0, 0, 0)"
      fg: "rgb(197, 202, 206)"
    hover:
      bg: "transparent"
      fg: "rgb(199, 204, 208)"
```

**Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand.


## 4c. Component Vocabulary (Closed System)

*This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.*

### Buttons
- **3 shape(s)** in this system: `Ghost`, `Pill`, `Secondary`
- **DO NOT introduce new buttons variants** without justification

## 5. Layout Principles

### Layout Type
**top-nav + content**

### Grid
Single column, centered content

### Max Width
1280px

### Spacing System
Generous spacing — editorial breathing room

| Token | Value |
|-------|-------|
| xxs | 2px |
| xs | 10px |
| sm | 16px |
| md | 24px |
| base | 80px |
| lg | 88px |
| xl | 96px |
| 2xl | 104px |
| 3xl | 112px |

### Border Radius Scale
| Name | Value | Use |
|------|-------|-----|
| None | 0px | No rounding |
| Xs | 6px | Tiny corners (badges, micro elements) |
| Sm | 12px | Buttons, inputs, small elements |
| Md | 16px | Cards, containers |
| Lg | 24px | Large rounded elements, pill segments |
| Xl | 9999px | Category strips, featured containers |
| Full | 9999px | Pills, avatars, circular elements |

### Shape Language

| Component | Border Radius |
|-----------|---------------|
| Buttons | `6px` |
| Page Body | `0px` |
| Navigation | `24px` |

**Shape Personality**: Generously Rounded — Soft, friendly corners (8px+). Approachable, consumer-facing feel.

**Full Radius Spectrum**: 6px, 12px, 16px, 24px, full/pill (from `allBorderRadii` scan)


## 5b. Spacing Rhythm Names

*Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.*

| Name | Value | Use case |
|------|-------|----------|
| **hero** | `112px` | Top/bottom of full-bleed hero sections |
| **section** | `96px` | Between major bands (color change, content shift) |
| **subsection** | `88px` | Within a section, between content groups |
| **card** | `24px` | Card padding, list-item spacing |
| **compact** | `16px` | Form fields, tight clusters, badge padding |
| **micro** | `10px` | Icon-text gap, tag inner padding |

**Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.).

## 5c. Widget & Structure Library

Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values).

**4/8 structural patterns detected.**

### Navigation Pattern

- **Position:** static (scrolls with page)
- **Layout:** logo-left-links-left — Logo and links both on the left (CTAs typically right)
- **Height:** 92px
- **Logo:** ✓ present
- **Nav links:** 9 primary items
- **CTAs in nav:** 1
- **Clone instruction:** Build a static logo left links left navigation. Reserve 1 slot for primary CTA.

### Card Grid Pattern

- **Card count:** 6 cards detected
- **Columns (desktop):** 4-up grid
- **Card dimensions:** 399×378px (aspect 1.06:1)
- **Gap:** 24px between cards
- **Content:** ✓ image + CTA
- **Image position:** top
- **Clone instruction:** Build a 4-column grid (desktop) with cards at ~1.06:1 aspect ratio. Each card has an image at the top.

### Testimonial Pattern

- **Count:** 6 testimonial blocks
- **Layout:** grid
- **Avg quote length:** 233 chars (long-form story)
- **Includes:** ✗ no avatars | ✗ no logos | ✗ no ratings
- **Clone instruction:** Build a grid of 6 testimonials.   

### Footer Pattern

- **Columns:** 1
- **Links:** 25 total
- **Height:** 537px
- **Includes:** ✗ no newsletter | ✓ social icons |  ✓ copyright
- **Clone instruction:** Build a 1-column footer with ~25 links per column, social media links, and a copyright line.

## 6. Depth & Elevation

| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow | Page background, content blocks |

**Shadow Philosophy**: Flat design — no shadows used. Borders and spacing define structure.

## 7. Motion & Interaction

### Dominant Easing Curves

| Curve | Semantic Name |
|-------|---------------|
| `cubic-bezier(0.4,0,0.2,1)` | Material Standard — Balanced |

### Duration Scale

| Value | Tier | Typical Use |
|-------|------|-------------|
| `150ms` | Fast | Hover states, micro-interactions |
| `200ms` | Normal | Panel open/close, navigation |

### Copy-Paste Transition Snippets

**All Props**
```css
transition: 0.15s cubic-bezier(0.4, 0, 0.2, 1);
```

**Color / Background**

### Motion Fingerprint

- **Speed Character**: Balanced Pacing (median duration: `200ms`)
- **Dominant Easing**: custom cubic-bezier curves
- **Animation Library**: 11 unique animations (11 total including variants)

> This design moves with balanced pacing timing using custom cubic-bezier curves, creating a UI that feels natural and fluid.

## 8. Do's and Don'ts

### Do
- Use dark background (`#0d1318`) as the foundation — this is a dark-mode-native design
- Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)
- Use #4ff7d1 (`#4ff7d1`) as the primary accent — it's the brand's signature interactive color
- Use pill-shaped radius (9999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs
- Maintain nav height at 92px — consistent vertical space for the navigation bar
- Respect the 10px–96px spacing range — the design uses a wide scale for visual breathing room
- Each card includes a top image — imagery is part of the card identity, not optional
- Use a 4-column grid on desktop — density matters for this content type
- Lay out testimonials in a grid (6+ items) — quantity signals scale and trust

### Don't
- Don't use light backgrounds — the dark canvas is the native medium
- Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements
- Don't introduce additional saturated accent colors — the palette is intentionally controlled
- Don't use rectangular buttons for primary actions — the rounded pill shape is the brand standard
- Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
- Don't make the nav sticky — this design lets it scroll away to maximize content focus


## 7b. Enforceable Brand Rules

*Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.*

```yaml
rules:
  - id: brand-canvas-001
    type: do
    rule: "Always use the page background `rgb(13, 19, 24)` as the base canvas"
    why: "Every component is designed to composit against this exact tone"
    test: "document.body.style.backgroundColor === 'rgb(13, 19, 24)'"
  - id: brand-accent-001
    type: do
    rule: "Reserve `rgb(79, 247, 209)` for primary CTAs and brand-mark signals only"
    why: "Single chromatic assertion device — overuse dilutes meaning"
    test: "querySelectorAll('[style*=\"rgb(79, 247, 209)\"]').length <= 3 per fold"
  - id: brand-depth-001
    type: dont
    rule: "Do NOT introduce drop shadows on cards or sections"
    why: "Containment is achieved via borders, not elevation — adding shadows breaks the depth contract"
    test: "getComputedStyle(card).boxShadow === 'none'"
```

## 9. Responsive Behavior

### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile Large | 576px | Expanded mobile layout |
| Mobile Large | 640px | Expanded mobile layout |
| Tablet | 768px | Multi-column grids begin |
| Tablet | 1024px | Multi-column grids begin |
| Desktop | 1280px | Full feature layout |
| Large Desktop | 1440px | Maximum content width |

### Token Diff — Desktop vs Mobile

| Element | Property | Desktop | Mobile |
|---------|----------|---------|--------|
| nav | height | `92px` | `112px` |
| button | width | `auto` | `24px` |

### Collapsing Strategy
- Navigation: horizontal links → hamburger menu on mobile
- Cards: multi-column → stacked vertical on mobile
- Footer: multi-column → stacked single column on mobile

### Touch Targets
- Buttons: 10px padding
- Navigation: adequate spacing between items
- Interactive elements: minimum 44px touch target recommended

### Collapsing Narrative

How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions):

- **Navigation collapses to hamburger** — 9 links visible on desktop, 1 on mobile (the rest hide behind a menu toggle).
- **Card grid: 4-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile.


## 7c. Visual Effects & Dynamic Behavior

*The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.*

- **Clip-path shapes** — 8 non-rectangular cut(s).

> **Motion fingerprint**: non-rectangular shapes (10)

## 9b. Visual Tone & Photography

**Tone:** No imagery

No detectable photographic content. The site composes entirely with typography, color blocks, and minimal vector graphics. Clone strategy: lean on type hierarchy + layout rhythm rather than visual media.

**Canonical Brand Image (OG):**
- https://turso.tech/opengraph-image.png?8abb64b5fd9d7c60 (2400×1260px)
  *This is the image shown when the site is shared on social media — represents the brand visual essence.*

**Media Format Mix:**
- SVG: 4 (icons, illustrations, decorative geometry)

**Decorative Patterns Detected:**
- 1 radial gradient — circular color blooms used for spotlight/glow effects
- 4 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents

**Clone instruction for decorative work:** Decorative SVG accents are part of the brand — generate or source blob/illustration shapes to scatter behind content.

**Imagery Guidance for clones:**
- Don't add stock imagery just to "fill space" — this site's clarity comes from typographic restraint.
- Use generous whitespace, strong type hierarchy, and color blocks for visual rhythm.

- Accent: #4ff7d1 (`#4ff7d1`)
- Border: Translucent Pure White (10%) (`rgba(255, 255, 255, 0.1)`)
- Font: __Inter_f367f3
- Body: 16px weight 400

### Example Component Prompts
- "Create the primary CTA button: `#4ff7d1` background, `#000000` text, 9999px border-radius, 12px 24px padding, 600 weight, __Inter_f367f3 font."
- "Build navigation: static on `#0d1318`. __Inter_f367f3 16px weight 400 for links."

### Iteration Guide
1. **Canvas**: Set the dark canvas to Jet Black (`#0d1318`) — every component is composited against this exact base.
2. **Typography**: All type in __Inter_f367f3, weight range 400–800. Never exceed 800 — heavier weights break the brand's tonal restraint.
3. **Accent**: #4ff7d1 (`#4ff7d1`) is the sole interactive color. On hover → #4ff8d2 (`#4ff8d2`). Use CSS transitions, not opacity/brightness filters.
4. **Motion**: All transitions use `cubic-bezier(0.4,0,0.2,1)`. Never use linear for UI transitions — preserve the brand's easing personality.
5. **Shape**: CTAs at `9999px`. Apply border-radius from the extracted scale only — don't invent intermediate values.
6. **Spacing**: Use the `--ca-space-*` token scale (10px–96px). All padding, margin, and gap values are multiples from this scale — no magic numbers.
7. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent.

## 11. CSS Design Tokens Raw Export

*Copy-paste ready `:root {}` block — all values extracted directly from the live site.*

## 13. Page Structure Skeleton

*The actual layout the source site uses. Reproduce these sections in order to match the site structure.*

```yaml
page-skeleton:
  - section: logo-strip
    tag: div
    classes: ["sticky", "top-0", "z-[100]", "border-y"]
    height: 94px
    width: full-bleed
    layout: block
    children: 1
    bg: "rgb(13, 19, 24)"
    tone: dark
  - section: header
    tag: header
    classes: ["transition-all"]
    height: 92px
    width: 1278px
    layout: block
    children: 1
    vertical-padding: ~24px

```

**Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block).


## 14. Copy Library (Real Content from Source)

*Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.*

```yaml
copy:
  section-headings:
    - "Millions of Databases. One Architecture."
    - "Why Agents Need a New Database"
    - "Don't just take our word for it"
    - "Join the Community"
  sub-headings:
    - "Turso"
    - "AI Agents"
    - "Turso SDKs"
  ctas:
    - "Login"
    - "Start for free now"
    - "npx turso@latest"
    - "COMPAT.md"
    - "Create Database"
    - "Read testimonial"
    - "Read Manual"
    - "Rust"
  navigation:
    - "Turso"
    - "Follow us on GitHub"
    - "Follow us on X"
    - "Join us on Discord"
    - "Docs"
    - "Cloud Pricing"
    - "Blog"
    - "Changelog"
    - "Login"
    - "Start for free now"
  footer-links:
    - "Quickstart"
    - "RSS"
```

**Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording.


## 15. Asset Inventory (Image Roles & Ratios)

*Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.*

```yaml
assets:
  thumbnail:
    count: 6
    avg-ratio: 1.00
    common-aspect: "~1:1 square"
    sample-alts:
      - "Mike Soylu"
      - "Simon Henrikson"
      - "Luke Kim"
```

**Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`.


## 16. Component HTML Templates

*Suggested HTML markup for reproducing the key components — based on what was detected in the source DOM.*

### Button (primary action)
```html
<button class="btn btn-primary">
  Login
</button>
```
_Source pattern detected: padding `8px 16px` · radius `9999px` · weight `600`_

**Agent rule**: use these markup skeletons as the structural baseline. Apply tokens from §2-3 for visual styling.


## 17. Content Architecture & Resources (Links by Purpose)

*The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.*

**By purpose:** **nav** 2 · **cta** 2 · **auth** 1 · **pricing** 2 · **docs** 16 · **blog** 10 · **social** 21 · **footer** 5 · **other** 1

**Primary actions (conversion path):**
- Account access — "Login" (login/signup) → `https://turso.tech/signin`
- Primary call-to-action — "Start for free now" (the conversion path) → `https://app.turso.tech/signup`
- Primary call-to-action — "Create Database" (the conversion path) → `https://app.turso.tech/signup`

## Extraction Completeness: 65/100 (C)

| Category | Score | Max | Detail |
|----------|-------|-----|--------|
| Colors & Palette | 25 | 25 | 19 named colors |
| Typography | 18 | 20 | 7 roles defined |
| Components | 4 | 20 | 1 specs extracted |
| Motion & Interaction | 12 | 15 | Keyframes |
| CSS Custom Properties | 1 | 10 | 22 vars |
| Responsive Breakpoints | 5 | 5 | 6 breakpoints |
| Variable Fonts | 0 | 5 | None detected |

## 12. Known Gaps & Confidence

Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback.

*Auto-detected extraction limitations — understand before building:*

- **Licensed web fonts (__Inter_f367f3)** — detected but not downloaded. Substitute with your licensed copy or a close fallback (see Typography section for metrics).
- **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass.

| Category | What's missing | Fallback strategy |
|----------|----------------|-------------------|
| **Photography** | No photographic content detected on this page | Don't add stock imagery; clarity comes from type + color blocks |
| **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside |

### Per-section confidence

| Section | Confidence | Reason |
|---------|------------|--------|
| §1 Visual Theme | High | Body bg extracted via getComputedStyle() |
| §2 Colors | Medium | 22 CSS vars (semantic naming requires ≥20 for high) |
| §3 Typography | High | 7 typography roles inferred |
| §4 Components | Low | 1 component variants captured |
| §7 Motion | High | Keyframes + transitions |
| §8 Do's/Don'ts | High | 15 rules generated; design-decisions.json has evidence per rule |
| §9 Responsive | High | 6 breakpoints detected |
| §9b Photography | Low | 0 images, hero not detected |

## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+)

*Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS). Copy-paste into your `<style>` block.*

### Font Loading

1 font file(s) captured (47KB total). When running `prism add`, fonts are saved to `extractions/turso.tech/fonts/` and embedded as base64 in the output HTML.

**@font-face declarations to use:**
```css
@font-face {
  font-family: '__Inter_f367f3';
  /* src: url('/fonts/__Inter_f367f3.woff2') format('woff2'); */
  font-weight: 100 900;
  font-style: normal;
  font-display: swap;
}
@font-face {
  font-family: '__Inter_Fallback_f367f3';
  /* src: url('/fonts/__Inter_Fallback_f367f3.woff2') format('woff'); */
  font-weight: normal;
  font-style: normal;
  font-display: swap;
}
```

### Keyframe Animations (Intercepted from CSS)

**4 @keyframes found** — these are the real animation definitions:

```
@keyframes ping { ... }
@keyframes spin { ... }
@keyframes bounceLinear { ... }
@keyframes floating { ... }
```

<details><summary>Full keyframes CSS (4 animations)</summary>

```css
@keyframes ping{75%,to{transform:scale(2);opacity:0}}
@keyframes spin{to{transform:rotate(1turn)}}
@keyframes bounceLinear{0%,to{transform:translateY(-25%);animation-timing-function:linear}50%{transform:translateY(0);animation-timing-function:linear}}
@keyframes floating{0%{transform:translate(0)}50%{transform:translateY(15px)}
```
</details>

### Brand Gradient Palette

**1 complex gradients captured** from the site's CSS. The first few are the most prominent visual decorations:

```css
/* Gradient 1 */
background: radial-gradient(ellipse 50% 50% at 50% 50%,#000 0,transparent 100%);

```

### Hover State CSS (Intercepted)

**1 hover rule lines** captured from CSS files. Key interactive transitions from real CSS (not inferred):

```css
@layer tursoComponents, reset, defaults, tursoBase, turso-text, module;@layer reset{blockquote,body,caption,div,fieldset,form,h1,h2,h3,h4,h5,h6,html,label,legend,p,pre{font-size:100%;font-weight:400;margin:0;padding:0;vertical-align:baseline;border:0;outline:0;background:transparent}table{border-spacing:0;border-collapse:collapse}td,th{text-align:left;vertical-align:middle}img{border:0}button,input,select,textarea{font:inherit}body{min-height:100vh}*,:after,:before{box-sizing:border-box}button,input[type=reset],input[type=submit]{all:unset}a{text-decoration:none;color:inherit}hr{margin-block-start:0;margin-block-end:0;border:none}::-moz-placeholder{opacity:1;color:inherit}::placeholder{opacity:1;color:inherit}figure,ul{margin-block-start:0;margin-block-end:0;margin-inline-start:0;margin-inline-end:0}ul{list-style-type:none;padding-inline-start:0}}@layer turso-text{.turso-display{font-size:4.768125rem}.turso-display,.turso-h1{font-family:var(--font-inter);font-style:normal;font-weight:700;line-height:110%;letter-spacing:-.03em}.turso-h1{font-size:3.815rem}.turso-h2{font-size:3.375rem}.turso-h2,.turso-h3{font-family:var(--font-inter);font-style:normal;font-weight:700;line-height:110%;letter-spacing:-.03em}.turso-h3{font-size:3.051875rem}.turso-h4{font-weight:600;font-size:2.44125rem;line-height:110%}.turso-h4,.turso-h5{font-family:var(--font-inter);font-style:normal;letter-spacing:-.03em}.turso-h5{font-weight:400;font-size:1.953125rem;line-height:100%}.turso-h6{font-family:var(--font-inter);font-style:normal;font-weight:700;font-size:1.5625rem;line-height:125%;letter-spacing:-.03em}.turso-label{letter-spacing:.1em;text-transform:uppercase}.turso-big-medium,.turso-label{font-weight:500}.turso-big-medium,.turso-big-regular,.turso-label{font-family:var(--font-inter);font-style:normal;font-size:1.25rem;line-height:150%}.turso-big-regular{font-weight:400}.turso-big-bold{font-family:var(--font-inter);font-style:normal;font-weight:600;font-size:1.25rem;line-height:150%}.tail
```

## 11.2 Measured Reality (CDP Engine)

Captured directly from Chrome's engine across **all 1265 rendered nodes** — not a sample. These are the values the page *actually paints*, weighted by how often they appear.

### Real Responsive Breakpoints
**9 breakpoints** read from the live `@media` rules (not guessed):
`576px` · `640px` · `768px` · `1024px` · `1200px` · `1280px` · `1440px` · `1536px` · `1920px`

### Measured Design Scale
**Type scale by usage** (× = paint count): `16px`×998 · `14px`×140 · `18px`×74 · `12px`×14 · `48px`×14 · `20px`×8 · `24px`×6 · `72px`×4

**Radius scale** (× = paint count): `9999px`×57 · `12px`×20 · `16px`×15 · `24px`×1

**Weights** (× = paint count): `400`×1069 · `600`×160 · `500`×27 · `800`×4 · `700`×4

**Layout gaps** (× = paint count): `normal 6px`×11 · `4px`×8 · `16px`×5 · `24px`×4 · `normal 24px`×1 · `normal 32px`×1 · `6px`×1 · `32px`×1

### Provenance — measured styles on key elements
Read from the live CSSOM (includes runtime-injected CSS). This is *what actually styles the page*, by element:

```css
body { font-family:var(--font-inter) }
body { background-color:rgb(13 19 24/var(--tw-bg-opacity)) }
body { color:rgb(255 255 255/var(--tw-text-opacity)) }
@media (min-width: 1280px) nav { border-radius:1.5rem }
h2 { font-size:2.25rem }
h2 { font-weight:800 }
h2 { color:rgb(79 248 210/var(--tw-text-opacity)) }
@media (min-width: 768px) h2 { font-size:3.75rem }
@media (min-width: 1024px) h2 { font-size:4.5rem }
button { border-radius:.375rem }
button { color:rgb(156 163 175/var(--tw-text-opacity)) }
```

> Selectors normalised to their semantic element — source class names are often build-hashed (`.bgDIHX`) and not reusable. The declarations + CSS vars are the transferable part.
